ABSTRACT Whereas Takhtajan and Smith situated the origin of angiosperms between Southeast Asia and Australia, Walker and Le Thomas emphasized the concentration of primitive pollen types of Annonaceae in South America and Africa, suggesting instead a Northern Gondwanan origin for this family of primitive angiosperms. A cladistic analysis of Annonaceae shows a basal split of the family into Anaxagorea, the only genus with an Asian and Neotropical distribution, and a basically African and Neotropical line that includes the rest of the family. Several advanced lines occur in both Africa and Asia, one of which reaches Australia. This pattern may reflect the following history: (a) disjunction of Laurasian (Anaxagorea) and Northern Gondwanan lines in the Early Cretaceous, when interchanges across the Tethys were still easy and the major lines of Magnoliidae are documented by paleobotany; (b) radiation of the Northern Gondwanan line during the Late Cretaceous, while oceanic barriers were widening; (c) dispersal of African lines into Laurasia due to northward movement of Africa and India in the Early Tertiary, attested by the presence of fossil seeds of Annonaceae in Europe, and interchanges between North and South America at the end of the Tertiary.

Political Radicalism

The Atlantic Ocean not only connected North and South America with Europe through trade but also provided the means for an exchange of knowledge and ideas, including political radicalism. Socialists and anarchists would use this “radical ocean” to escape state prosecution in their home countries and establish radical milieus abroad. However, this was often a rather unorganized development and therefore the connections that existed were quite diverse. The movement of individuals led to the establishment of organizational ties and the import and exchange of political publications between Europe and the Americas. The main aim of this book is to show how the transatlantic networks of political radicalism evolved with regard to socialist and anarchist milieus and in particular to look at the actors within the relevant processes—topics that have so far been neglected in the major histories of transnational political radicalism of the late nineteenth and early twentieth centuries. Individual case studies are examined within a wider context to show how networks were actually created, how they functioned and their impact on the broader history of the radical Atlantic.

This book describes the experience of Jewish refugees as they fled Hitler to live in limbo in Portugal until they could reach safer havens abroad. As the Nazis launched the Holocaust, Lisbon emerged as the best way station for Jews to escape Europe for North and South America. Jewish refugees had begun fleeing the continent in the mid-1930s from ports closer to home. But after Germany defeated Belgium, the Netherlands, Luxembourg, and France, and Italy joined the war, all in the spring of 1940, Lisbon became the port of departure from Europe. Jewish refugees from western and eastern Europe aimed for Portugal. An emotional history of fleeing, the book probes how specific locations touched refugees' inner lives, including the borders they nervously crossed or the overcrowded transatlantic ships that signaled their liberation.

Caimanines are crocodylians currently restricted to South and Central America and the oldest members are from lower Palaeocene localities of the Salamanca Formation (Chubut Province, Argentina). We report here a new caimanine from this same unit represented by a skull roof and partial braincase. Its phylogenetic relationships were explored in a cladistic analysis using standard characters and a morphogeometric two-dimensional configuration of the skull roof. The phylogenetic results were used for an event-based supermodel quantitative palaeobiogeographic analysis. The new species is recovered as the most basal member of the South American caimanines, and the Cretaceous North American lineage ‘ Brachychampsa and related forms' as the most basal Caimaninae. The biogeographic results estimated north-central North America as the ancestral area of Caimaninae, showing that the Cretaceous and Palaeocene species of the group were more widespread than thought and became regionally extinct in North America around the Cretaceous–Palaeocene boundary. A dispersal event from north-central North America during the middle Late Cretaceous explains the arrival of the group to South America. The Palaeogene assemblage of Patagonian crocodylians is composed of three lineages of caimanines as a consequence of independent dispersal events that occurred between North and South America and within South America around the Cretaceous–Palaeogene boundary.

Slavery had long existed in Europe and Africa, but the history of the Atlantic slave trade begins in the 1440s with Portuguese exploration of West Africa. ‘The Atlantic slave trade’ charts the increased demand for slave labor in Portugal and the Christian justification of African enslavement. In the 1490s, the journeys of Christopher Columbus to the Caribbean and North and South America opened up mineral-rich and fertile lands on which European countries planted their flags and the Christian cross. More than 12 million Africans boarded the ships, but nearly 2 million died during the Middle Passage. Of those who survived, only about 5 percent went to North America, with most going to South America and the Caribbean.

Presented by the Central American Actuarial Association (Asociacion Acturial Centroamericana) to the 13th ASTIN Colloquium.The Asociaciôn Actuarial Centroamericana (AAC) is a grouping of Actuaries from the Central American Republics of El Salvador, Guatemala, Honduras, Nicaragua, Costa Rica and Panama. The AAC is a contributing ASTIN member of the International Actuarial Association.Earthquakes have been a constant scourge of mankind. Central America has not escaped this phenomenon, indeed the territory has been most affected by them precisely because of its condition as an isthmus that serves as a fragile union between the continental land masses of North and South America, and in consequence being subject to disturbances by the displacement of the continental plates. Our lands abound with beautiful volcanoes, which have also contributed to local seismic activity. Whatever their origin, the earthquakes that have struck our country have left their share of destruction of lives and property.In Annex 1 a table is presented, showing a history of seismic activity and volcanic eruptions in the countries on the Caribbean Platform, in which we can appreciate in detail the catastrophes that occurred from the XVI Century until 1976.

IT is well-known that the Franciscans had a very considerable influence on the history of America. From the days of the conquest up to the present time, their labors have been outstanding in the sphere of American spiritual life by their extensiveness, their intensity, and their brilliance. In the missionary field, Franciscan activity was particularly conspicuous. Up to the end of the sixteenth century, the Franciscan missions were almost as numerous as those of all the rest of the religious orders together; Franciscan primacy was maintained in the seventeenth century, and from 1767 onwards nearly all the missions among the pagans, both in North and South America, remained in their hands, once the Society of Jesus had been suppressed.
